GRANTS PASS, Ore. (AP) — Rescuers are hoping for a break in the weather to evacuate two injured backcountry skiers who survived an avalanche that killed two others in northeastern Oregon's Wallowa Mountains. Baker County Undersheriff Warren Thompson said Wednesday morning that two National Guard helicopters were flying to the site. He says there's no word on whether there's enough visibility for the helicopters to pick up the two injured skiers, who were bundled in rescue sleds after a cold and snowy night on the mountain. Four unhurt skiers were taken out by a snow cat, which couldn't reach the injured skiers on the steep slope. Most of the skiers were from the Seattle area. They were on a guided five-day trip with an outfitter from Joseph.
